What Are All On 4 Dentures?

If you need to replace your teeth — due to years of wear, chronic decay, gum disease, or something else — All-on-4 dental implants offer a straightforward and long-lasting alternative to wearing conventional removable dentures.

A Hybrid Denture Design

All-on-4 treatments feature a streamlined, hybrid denture design that follows the contour of your jaw, rather than covering the entire roof of your mouth the way a “plate” would.

The entire prosthesis is permanently affixed to four strategically placed implants, which support the biting and chewing forces in a way that resembles the function of healthy, natural teeth.

Only four implants are necessary because each one can withstand the weight and pressure of multiple teeth. Placing them in key points across the jaw allows a full-arch prosthesis to be stabilized in a predictable manner.

Permanent, Stabilized Full Arch Design

Conventional dentures and partials have to be taken out each night, making them tough on your gum tissues and the bone underneath that supports them. But with an All-on-4 denture you can have a permanent full mouth restoration that never comes in and out of place. You eat, sleep, and live with it 24 hours a day. This makes them healthier for your mouth overall, as implants aid in strengthening the bone and preventing sunken-in facial tissues associated with missing teeth.

How to Care for All-on-4 Dentures

We recommend that all implant patients care for their smiles as if they were made up of natural teeth. Daily brushing and flossing are essential to keep the gingival tissues around each implant healthy and free of infection. Because it can take some practice to thread floss under a fixed restoration such as an All-on-4 prosthesis, there is also the option of investing in a water flosser to use instead.

Continue to schedule regular preventative care appointments every six months to ensure any issues are intercepted as early as possible.

What to Expect from Treatment

Getting an All-on-4 denture is similar to our other dental implant treatments, in that the biocompatible, artificial roots are set into the mouth and a healing prosthesis is affixed to them until full osseointegration occurs. From there, we change the restoration out with a permanent one (unless immediate placement the day of treatment is an option.)

Today’s implant treatments can be digitally mapped out well in advance, aiding in a simpler and straightforward placement on the date of treatment. This 3D visualization makes it possible to select the most optimal location for each of the four supporting dental implants, taking advantage of natural oral anatomy and minimizing additional treatments such as bone grafts or sinus lifts.

Choosing an Implant Provider

Selecting the right an All-on-4 implant dentist is an essential step in ensuring a predictable and optimal outcome for your smile.
